The composition of molybdate-based conversion coatings on zinc–nickel alloy electrodeposits was examined by extended X-ray absorption fine structure (EXAFS). The absorption spectra from appropriate standards showed distinct differences between the

6063 aluminium alloys were AC anodized in molybdate containing and molybdate free sulphuric acid solutions. The total impedance of the oxides produced in molybdate containing solutions decreased faster in 0.01 N HCl and after 8 days, following the di

A key characteristic property of thin anodic oxide films is the apparent film density which shows significant variation from the conventionally quoted value for thick films. Knowledge of its value is important for the calibration of the films thickne

The sealing of porous anodic oxide films on aluminium by the use of nickel fluoride solutions at ambient temperatures has been proposed as an alternative to hydrothermal sealing methods, on energy grounds. The process of cold sealing shows some promi

Although the key in present cold seating solution formulation practice is the presence of nickel fluoride, its performance can be optimized through the use of other parameters. In particular the ef...

This paper investigates the effect of varying sealing parameters, in order to optimize the conditions used to achieve a good seal quality for nickel fluoride cold sealed anodized aluminium. The eff...

SUMMARYThe performance of accelerated aged (post-treatment) nickel fluoride cold sealed finishes is compared with those of room temperature aged and conventional hydrothermal sealed finishes. It was found that accelerated ageing at temperatures of 60

Aluminium is generally regarded as a metal that is difficult to plate. By using a pretreatment sequence, which includes immersion in a zincate solution, it is possible to electroplate aluminium successfully, although adhesion levels are not always ve

A commercially available modified alloy zincate solution with various metal ion additions has been used to produce immersion films on aluminium, enabling it to be electroplated with other metals to attain good adhesion. The effects of nickel, iron, c

Studies have implicated Ca++ in the actions of ethanol at many biochemical levels. Calcium as a major intracellular messenger in the central nervous system is involved in many processes, including protein phosphorylation enzyme activation and secreti
